The sun's rays have a greater effect on land temperature than they have on water temperature. This can be explained partly by which of the following? (1) Some energy from the sun is used to evaporate ocean water.
(2) Less energy is reflected by the water's surface than by the land's surface.
(3) Land materials have a higher specific heat than water has.
(4) Land Materials require more heat energy than water does to raise their temperature 1 degree Celsius.

Steelhead trout migrate up stream to spawn.occasionally they need to leap up small waterfalls to continue their journey. fortunately, steelhead are remarkable jumpers, capable of leaving the water at a speed of 8.0 m/s. a. what is the maximum height a steelhead trout can jump? b.leaving the water at 8.0 m/s, the trout lands on top of the water fall 1.8 m high. how long was it in the air?

First answer marked as brainiest which is the correct equation describing the first law of thermodynamics? a) when the internal energy of a system changes, it equals the amount of heat added plus the work done. b) when work is done by the piston, it is equal to the heat added plus the change in internal energy of the system. c) when heat is added to the system, it is equal to the amount of work done by the piston plus the change in internal energy of the system.
